Matthew 16New King James Version (NKJV)
The Pharisees and Sadducees Seek a Sign
16 Then the Pharisees and Sadducees came, and testing Him asked that He would show them a sign from heaven. 2 He answered and said to them, “When it is evening you say, ‘It will be fair weather, for the sky is red’; 3 and in the morning, ‘It will be foul weather today, for the sky is red and threatening.’ Hypocrites![a] You know how to discern the face of the sky, but you cannot discern the signs of the times.
